Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application is a continuation-in-part of application
Ser. No. 10/348,045, filed Jan. 20, 2003, the contents of which are
hereby incorporated in its entirety.
BACKGROUND OF THE INVENTION
[0002] The invention generally relates to insect screens, such as
for window or door units, screen porches, or other applications.
Recently, new materials have been proposed for insect screening.
These new materials are generally thinner than conventional
screening materials and provide for improved visibility through the
screening material.
[0003] Due to the small element diameter of the new insect
screening materials, these screening materials present new
challenges in tensioning and maintaining tension as the screening
is disposed within a frame. Therefore, a need exists for an
improved insect screen frame assembly capable of maintaining
smaller element diameter screening material in tension.
SUMMARY OF THE INVENTION
[0004] In accordance with the present invention, there is provided
an insect screen. The screen includes a frame assembly comprising a
series of frame members, each frame member having a first adhesive
and a screen tensioning groove. A cover is configured to engage
each frame member. The cover comprises a screen tensioning rib
configured to be inserted into the screen tensioning groove and a
second adhesive. Screening is initially held by the frame member
and the first adhesive, and as the cover is rotatably applied, the
screening is tensioned by the screen tensioning rib as it urges the
screen into a position where it is disposed into the screen
tensioning groove. The screen tensioning rib holds the screening in
tension between the frame member and the cover. The second adhesive
is positioned between the screening and the cover, in contact with
the screening, so as to hold the cover in place after being
rotatably applied to the screening. It is useful for the first and
second adhesives to be sufficiently conformable to allow them to
pass through the openings in the screening and adhere to the
surface on the opposite side of the screening. It is also useful
for the covers to have hook portions that fit over the outer edges
of the frame members to aid in positioning. In some embodiments,
the hook portions can also assist in holding the screen in place
during the installation of the covers.
[0005] There is also provided a method for maintaining the position
of screening under tension in a frame. The method includes
providing a frame member comprising a screen contact surface, a
first adhesive, and at least one screen tensioning groove. The
screening is held in a fixed position by the first adhesive to the
frame member. The method also includes providing a cover comprising
a frame member contact side and a non-contact side opposite the
frame member contact side. A screen tensioning rib is located on
the frame member contact side and is configured to be disposed
within the screen tensioning groove. A second adhesive is disposed
on the frame member contact side and the cover is rotatably pressed
against the frame member, so that the second adhesive, on the frame
member contact side of the cover, is disposed against the screening
110 as it is pressed against the frame member. As the cover is
rotated, the screen tensioning rib urges the screen into the screen
tensioning groove, thereby tensioning the screening. A portion of
the screening is disposed between the second adhesive and the frame
member.

DETAILED DESCRIPTION
[0019] The present invention is applicable to many different types
of window or door units that include insect screening in proximity
to the windows or doors. For simplicity, the invention will be
described mostly in the context of a window, although the invention
can also be used with a door, screen porch, recreational vehicle,
and other applications. FIGS. 1-4 illustrate one particular
embodiment of an insect screen 90 including a frame assembly 100 in
accordance with the invention. Insect screening 110 covers the
frame opening defined by inner frame perimeter 101. The insect
screen frame assembly 100 can be engaged to a frame surrounding
window glass, a sash frame, a casement frame, or a frame of any
window or patio door type or combination. The window is capable of
being opened or closed. The window can be, for example, a bay
window, bow window, projection window, a double-hung window, a roof
window, egress window, an awning window, a casement window, a
gliding window, and the like. In addition, the insect screen frame
assembly can be used in a screen porch or other environment without
an adjacent window or door, but is not restricted thereto.
[0020] Typically as shown in FIG. 1, the frame assembly 100 can
include two pairs of opposed frame members engaged with
corresponding covers. A first pair of opposed frame members
includes a bottom rail 102 and a top rail 104 that are oriented
parallel to a horizontal frame axis. A second pair of opposed frame
members includes a first side stile 106 and a second side stile 108
that are oriented parallel to a vertical frame axis. The four frame
members 102, 104, 106, and 108 can generally form a square or
rectangle shape. However, the insect screen 90 can be any shape and
can include different numbers of frame members. The joinery of the
frame assembly 100 can have a mortise and tenon appearance as is
shown in FIGS. 1-4. Alternatively, the frame assembly can have a 45
degree miter appearance. Further, a frame assembly could have
mortise and tenon joinery on the bottom rail to stile joints and 45
degree miter joinery on the stile to top rail joints. The frame
members can be joined structurally by corner keys that insert into
the hollow described by the frame member profile. FIG. 13
represents one such corner key and frame member profile. Another
way to structurally join the frame members is to include geometry
such as a screw chase in the frame member profile that can accept
fasteners. There are many known ways that frame members can be
joined as would be apparent to one skilled in the art, all of which
are encompassed herein.
[0021] Referring again to FIG. 4, the insect screen frame assembly
100 can also include locking clips 150 and 152 to lock assembly 100
to a frame, such as the frame of a window or door. Locking clips
150 and 152 also incorporate handles 154 and 158 that allow easier
removal of assembly 100 from a frame of a window or door. Locking
clip 150 is shown with more detail in FIG. 5. Locking Clip 152
comprises a similar configuration as locking clip 150, and is
substantially a mirror image of locking clip 150. Preferably, for
easier access for replacement, repair, or other manipulation, the
locking clips 150 and 152 are positioned on the side of the frame
assembly that face the interior of a structure that they are used
within.
[0022] Handles 154 and 158 are included on locking clips 150 and
152 to enable a user to more effectively manipulate frame assembly
100 or locking clips 150 and 152. Handle 158 is shown extending
outward from the interior side of the frame assembly 100 in FIG. 2.
However, alternative embodiments are possible in which handles 154
and 158 do not extend outward from frame assembly 100. Generally, a
user can position bottom rail 104 in a corresponding groove located
in a window or door unit. The user then moves bottom rail 102 of
frame assembly 100 toward the window until bottom rail 102 is tight
with the frame of the window or door unit. The user slides locking
clips 150 and 152 away from the center of bottom rail 102 toward
locking clip receiving apertures of a frame (not shown) of a window
or door unit until catch 156 of clip 150 and its counterpart catch
in clip 152 slide into catch receiving apertures of the frame. The
user can slide locking clips 150 and 152 away from the center of
bottom rail 102, into locking clip receiving apertures using
handles 154 and 158. Alternatively, locking clips 150 and 152 can
be connected to spring mechanisms, which automatically bias locking
clips 150 and 152 away from the center of rail 102, toward locking
clip receiving apertures.
[0023] FIG. 13 shows an exploded view illustrating the assembly of
bottom rail 102 with stile 106. In an alternative embodiment,
bridge 196 is shown in the profile of frame member 116. Bridge 196
typically adds support to frame member 116, although such support
is not necessary to the invention. Bridge 196 can also assist the
insertion of corner key 181 into frame member 116. Corner key 181
is generally shown as a "T" shape. However, corner key 181 can also
generally comprise an "L" shape or a variety of other shapes while
remaining within the scope of the invention. During assembly, lock
197 can be inserted in the end of frame member 116. Next, tab 198
can be inserted into a corresponding frame member, such as stile
106, thereby forming the frame assembly. In some embodiments, it
may be desirable to use adhesive on lock 197 or tab 198 to further
secure the corner keys to the frame members.
[0024] Screening 110 is disposed within the open area defined by
inner frame perimeter 101 of insect screen frame assembly 100.
Screening 110 generally defines a portion of a plane and includes a
plurality of individual elements. Element 112 is shown parallel to
stile 106 and stile 108. Element 114 is shown parallel to bottom
rail 102 and top rail 104. However, the elements of screening 110
can comprise a variety of configurations. Openings 132 are located
between individual elements of screening 110. The size of openings
132 depends on the distance between the horizontal and vertical
screening elements. The screening 110 shown in FIGS. 1, 3, and 4 is
not drawn to scale, for ease of illustrating the individual
elements. The claimed screen frame is particularly useful for
screening materials having smaller screen element diameters than
conventional screens.
[0025] In one embodiment, the insect screening material includes
screen elements having a diameter of about 0.005 inch (0.13 mm) or
less. The screen elements have a tensile strength of at least about
5500 psi (37.921 mega Pascals). The light transmittance of the
screening 110 is at least about 0.70 and the reflectance of the
screening 110 is about 0.04 or less to reduce the visibility of the
screening. Examples of screening 110 are discussed in U.S. patent
application Ser. Nos. 10/068,069 and 10/259,221, both titled
"REDUCED VISIBILITY INSECT SCREEN" and filed on Feb. 6, 2002 and
Sep. 26, 2002, respectively, which are incorporated herein by
reference.
[0026] FIG. 6 shows a cross sectional view of bottom rail 102.
Element 112 is shown disposed within bottom rail 102. FIG. 7 shows
a cross-sectional view of top rail 104. In a preferred embodiment,
the cross-sections of stiles 106 and 108 are identical to the cross
section of top rail 104, however, a variety of configurations are
possible within the scope of the invention. For example, all rails
and stiles could have the same dimension W or a different dimension
W. It is preferred that dimension T of the rails and stiles be the
same, so as to provide a frame of uniform thickness after
joining.
[0027] With reference to FIGS. 6-8, the details of the
cross-sectional configuration of the rails and stiles will now be
discussed. The cross sectional view of stile 106 is shown in FIG. 8
during assembly. However, bottom rail 102, top rail 104, and stile
108 generally comprise similar cross-sectional configurations with
similar components. Referring to FIG. 8, stile 106 is generally
comprised of frame member 116 and cover 120. Cover 120 is
configured to engage frame member 116 with screening 110 generally
disposed between cover 120 and frame member 116. The frame member
116 includes groove 134 suitable for engaging hook portion 163 of
cover 120.
[0028] With reference to frame member 116 the inner portion 117 is
defined as the portion of the frame member 116 between the screen
tensioning groove 118 and the inner frame perimeter 101. The outer
portion 119 of the frame member 116 is defined as the area of the
frame member 116 between the screen tensioning groove 118 and the
outer frame opening 162 where the screening 110 first comes into
contact with the rail or stile. A frame assembly 100 is multiple
frame members joined to enclose an inner frame perimeter 101 area
for screening, such as four frame members joined in a rectangle,
before the covers are added. Preferably, the screen tensioning
groove 118 extends continuously around the frame assembly 100.
[0029] With reference to cover 120, the inner portion 123 is
defined as the portion of the cover 120 between screen tensioning
rib 122 and the inner cover perimeter 161. The outer portion 121 of
the cover 120 is defined as the area of the cover between the
screen tensioning rib 122 and the outer cover opening 163 where the
screening 110 first comes into contact with the rail or stile.
Frame member 116 includes a screen tensioning groove 118 disposed
in the surface of the frame member 116 that engages the cover 120.
Screen tensioning groove 118 is generally parallel to the outer
frame perimeter 162. Cover receiving groove 136 can also be located
on frame member 116. Groove 136 is useful for positioning cover 120
with respect to frame member 116. Groove 136 is preferably located
along the outer frame perimeter 162 of the frame member 116,
although alternative locations are possible.
[0030] FIG. 7 shows a cross sectional view of top rail 104, with
screening 110 installed. With reference to frame member 516 the
inner portion 517 is defined as the portion of the frame member 516
between the screen tensioning groove 518 and the inner frame
perimeter 501. The outer portion 519 of the frame member 516 is
defined as the area of the frame member 516 between the screen
tensioning groove 518 and the outer frame perimeter 562.
[0031] With reference to cover 520, the inner portion 523 is
defined as the portion of the cover 520 between the screen
tensioning rib 522 and the inner cover perimeter 561 where the
screening 110 first comes into contact with top rail 104. The outer
portion 521 of the cover 520 is defined as the area of the cover
520 between the screen tensioning rib 522 and the outer cover
perimeter 563.
[0032] Frame member 516 includes a screen tensioning groove 518
disposed in the surface of the frame member 516. Screen tensioning
groove 518 is generally parallel to the outer frame perimeter 562.
Groove 536 can also be located on frame member 516. Groove 536 is
useful for positioning cover 520 with respect to frame member 516.
Groove 536 is preferably located along the outer frame perimeter
562 of the frame member 516, although additional locations are
possible. Other mechanical engagement means could be used as would
be apparent to one skilled in the art.
[0033] In FIG. 8, cover 120 is shown being brought into engagement
with frame member 116, after positioning screening 110 on first
adhesive layer 130. Cover 120 includes screen tensioning rib 122
positioned to engage screen tensioning groove 118. The combination
of screen tensioning rib 122 and screen tensioning groove 118 are
useful for providing pressure against screening 110 to keep
screening 110 in tension between rails 102, 104 and stiles 106,
108. For example, cover 120 is shown at an angle of about 8 degrees
with respect to frame member 116 as the cover 120 is positioned on
the frame member 116 during assembly. At an 8 degree angle, screen
tensioning rib 122 contacts screening 110 and pushes some elements
of screening 110 into screen tensioning groove 118. This action
tensions screening 110 and provides additional friction to keep
screening 110 in tension. Screen tensioning rib 122 can contact
screening 110 when cover 120 is at a variety of angles with respect
to frame member 116. For example, exemplary contact angles range
from 5 degrees to 35 degrees. Higher contact angles generally
secure screening 110 with more tension than lower contact angles of
the cover 120 and frame member 116. When the installation of cover
120 is completed, second adhesive 124 contacts and adheres to
screening 110, thereby holding the screening in place. It is useful
for adhesive 124 to be sufficiently conformable to allow it to flow
through the openings in screening 110 and adhering to inner portion
117 of frame member 116.
[0034] Screen tensioning rib 122 is shown with a generally
elongated shape. However, screen tensioning rib 122 can comprise a
variety of configurations while serving the function of tensioning
screening 110 and maintaining screening 110 in tension. For
example, screen tensioning rib 122 can also be jagged, elliptical,
or of any other suitable shape, as would be apparent to one skilled
in the art. Screen tensioning rib 122 is shown extending from cover
120 at approximately a 90 degree angle. However screen tensioning
rib 122 can extend from the cover 120 at a variety of angles. In a
preferred embodiment, screen tensioning rib 122 extends from the
cover at an angle between 80 and 100 degrees.
[0035] Cover 120 can also include hook 134. Hook 134 is used to
engage groove 136 on frame member 116. The combination of hook 134
and groove 136 is useful for positioning cover 120 with respect to
frame member 116, and for resisting creep that could occur in the
adhesive layers due to tension in screening 110. Other mechanical
engagement means could be used as would be apparent to one skilled
in the art. In an alternative embodiment, the outer perimeter of
screening 110 can extend beyond outer perimeter 134 of frame member
116, so that when cover 120 is installed, screening 110 is captured
between hook portion 134 and groove 136, thereby aiding in
tensioning of screening 110 as cover 120 is rotated into place.
[0036] Second adhesive 124 can be a pressure sensitive, hot melt,
or other suitable adhesive. In a preferred embodiment, adhesive 124
includes a high performance pressure sensitive tape. A high
performance pressure sensitive tape is generally defined as capable
of essentially permanently supporting loads of greater than 300
grams per square centimeter of adhesive at temperatures of
150.degree. F. (65.degree. C.) or higher.
[0037] In addition to contacting screening 110, adhesive 124 can
also contact the engaging surface of frame member 116 through
openings 132 in screening 110. This configuration is believed to
further secure screening 110.
[0038] In another embodiment, a first adhesive 130 can be disposed
on frame member 116. A first adhesive 130 is shown on the surface
of frame member 116 between screen tensioning groove 118 and groove
136 on the outer portion 119 of the frame member. First adhesive
130 can comprise double sided tape or hot melt adhesive. In a
preferred embodiment, first adhesive 130 also includes a high
performance adhesive or pressure sensitive tape. Adhesive 130
preferably exhibits a non-creep property, which prevents screening
110 from losing tension within the frame assembly 100. In addition
to contacting screening 110, adhesive 130 can also contact the
engaging surface of cover 120 through openings 132 in screening
110. This configuration is believed to further secure screening
110. First adhesive 130 is useful for holding screening 110 in
place prior to tensioning by cover 120, and for holding the outer
edges of screening 110 in place during tensioning, so that
displacement of screening 110 by tensioning rib 122 occurs in the
inner area of screening 110, rather than at the outer perimeter,
thereby tensioning screening 110.
[0039] The first and second adhesives for attaching the screening
110 to the frame member 116 and cover 120 can be the same or
different. Suitable adhesives for each application include those
having sufficient shear strength and creep resistance to hold the
screen in tension for significant periods of time. Pressure
sensitive adhesives can be used, provided that they have sufficient
shear strength and resistance to creep. An additional feature
useful for pressure sensitive adhesives is that they have a level
of conformability sufficient to allow them to pass through the open
areas of the screening 110 and adhere to the adjacent frame member
or cover. Pressure sensitive adhesive systems particularly useful
in this regard are those comprising foam backings having pressure
sensitive adhesive layers attached to each major surface
thereof.
[0040] Foams particularly useful as backings for pressure sensitive
adhesives in the present invention are those commonly referred to
as syntactic foams. A syntactic foam comprises a polymeric matrix
surrounding hollow microbeads, microballoons, or microbubbles, as
they are variously called. Hollow microbeads made of flexible
polymeric materials are preferred, since they provide the foam
backing with flexibility, and hence conformability, while at the
same time contributing to the strength of the foam material under
various conditions of tensile and shear loading. In forming the
polymeric matrix for the foam, crosslinkable polymeric materials,
in particular acrylates and methacrylates have been found useful.
Useful foams are disclosed in U.S. Pat. No. 6,103,152, incorporated
herein by reference.
[0041] In producing the pressure sensitive adhesive layers attached
to the foam backing, crosslinked pressure sensitive adhesives,
especially acrylic adhesives, have been found useful. Examples of
useful adhesives are disclosed in U.S. Pat. No. 5,695,837, and in
U.S. Pat. No. 6,448,337, both incorporated herein by reference. It
is also contemplated that some pressure sensitive adhesives can
undergo post-application treatments, such as heat curing, to
improve adhesion, provided that such curing can be performed
without producing adverse effects such as loss of screen tension.
An especially useful class of pressure sensitive adhesive materials
is the VHBFM line of foam tapes, commercially available from 3M
Company, St. Paul, Minn.
[0042] In an alternative, the first and second adhesive can
comprise a hot melt adhesive. Hot melt adhesives are resinous
adhesives, which achieve a solid state and resultant strength by
cooling. Before heating, a hot-melt adhesive is a thermoplastic,
100% solid material. Upon the application of heat, the usual
operating temperature is in the range of 175 to 205 deg. C. (350 to
400 deg. F.), the material changes to a fluid state. Once the heat
is removed, the adhesive sets by simple cooling.
[0043] One or more fasteners (not shown) can also fasten cover 120
to frame member 116. The fasteners can comprise a variety of forms
including staples, nails, screws, bolt, hinged mechanisms, welds,
snap fits, or latches. Fasteners can operate in conjunction with
adhesives 124 and 130. In an alternative embodiment, a fastener can
operate without the use of any adhesive on cover 120 and frame
member 116. Fasteners can allow the cover to be tightened over time
and further tension the screening. For example, tightening the
fasteners could bring the screen tensioning rib into further
engagement with the screen tensioning groove to further tension the
screening.
[0044] Cover 120 and frame member 116 can be constructed from a
variety of materials. In a preferred embodiment, cover 120 and
frame member 116 are formed from aluminum. However, in alternative
embodiments, any one or both of cover 120 and frame member 116 can
be formed from a thermoplastic material, roll-formed steel, a
PVC/wood fiber composite, or other composite materials. Examples of
PVC/wood composite material are disclosed in U.S. Pat. Nos.
5,441,801; 5,486,553; 5,497,594; 5,518,677; 5,539,027; 5,695,874;
5,773,138, the disclosures of which are incorporated herein by
reference.
[0045] With reference to FIGS. 9-12, a method of constructing an
insect screen will now be discussed. First, screening 110 is
clamped between support fixture members 910 and 920 and while being
adjusted to be fairly evenly positioned within the support
structure. Members 910 and 920 are held together by bolts, clamps,
or any other suitable holding devices, as would be apparent to one
skilled in the art. Support fixture members 910 and 940 can
comprise a square, rectangle, or other shape, preferably
corresponding to but slightly larger than the shape of the frame
assembly 100. Referring to FIG. 10, frame assembly 100 is elevated
above surface 940 by base support 930. Once screening 110 is
clamped between support fixture members 910 and 920, screening 110
is placed over frame assembly 100, as shown in FIG. 11, so that
screening 110 contacts first adhesive layer 130. Base support 930
rests on surface 940. Base support 930 is also rectangular or
corresponds to the shape of the frame assembly.
[0046] Once screening 110 has been placed in contact with first
adhesive layer 130, it can be pressed down, using a roller or other
suitable means, as would be apparent to one skilled in the art, to
produce an adhesive bond. Screening 110 can then be trimmed around
outer perimeter 950 of frame assembly 100, so as to enable support
fixture members 910 and 920 to be removed, along with the excess
screening, resulting in the subassembly shown in FIG. 12.
[0047] Finally, covers are installed by hooking them into
peripheral groove 915 and rotating them into place until the
tensioning ribs urge screening 110 into the tensioning grooves.
After hooking, adhesive 124 on covers 120 contacts the screening
110, thereby bonding adhesive 124 to screening 110 and holding
screening 110 in tension and further providing some bonding of the
cover to the frame members through the openings in the screening.
The covers 120 are installed for each of the stiles and rails to
form the insect screen frame assembly 100.
[0048] The foregoing description of various embodiments of the
invention has been presented for the purposes of illustration and
description. It is not intended to be exhaustive or to limit the
invention to the precise form disclosed. Many modifications and
variations are possible in light of the above teaching. It is
intended that the scope of the invention be limited not by this
detailed description, but rather by the claims appended hereto.
